本地开发期间'TemplateDoesNotExist at /'错误

Question

我正在关注用于部署我的应用程序的django和mozilla教程。 我设置了一个虚拟env和基本设置，本地设置，等等，当我跑的命令：

./manage.py runserver 0:8000 --settings=Books.settings.local

浏览器显示错误，模板家里没有发现...... 我觉得可能是由于env的一些问题，我不确定。

Template-loader postmortem 

Django tried loading these templates, in this order: 

Using engine django: 

django.template.loaders.filesystem.Loader: /home/user/workspace/Books/Books/templates/home.html (Source does not exist) 
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/django/contrib/admin/templates/home.html (Source does not exist) 
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/django/contrib/auth/templates/home.html (Source does not exist) 
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/star_ratings/templates/home.html (Source does not exist) 
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/crispy_forms/templates/home.html (Source does not exist) 
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/debug_toolbar/templates/home.html (Source does not exist) 

另外我有更新manage.py如下：

import os 
import sys 

if __name__ == "__main__": 
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Books.settings.local") 

Answer 1

这条线：

BASE_DIR = os.path.dirname（os.path.dirname（os.path.abspath则（__ FILE__）））

指定BASE_DIR如父母您的base.py所在的当前目录的目录。这意味着BASE_DIR将把/home/user/workspace/Books/Books/

你应该试试这个：

PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__)) 
BASE_DIR = os.path.dirname(PROJECT_ROOT) 

，然后在TEMPLATES:：

TEMPLATES = [ 
    { 
     ... 
     'DIRS': [os.path.join(PROJECT_ROOT,'templates')], 
     ... 
]
